THE COMPONENTS IDENTIFIED BY MARK ARE CRITICAL FOR SAFETY.
REPLACE ONLY WITH PART NUMBER SPECIFIED.
VOLTAGE (MEASURED WITH VOLTMETER) IS DC VOLTAGE. (NO INPUT SIGNAL)
ELECTROLYTIC CAPACITORS ARE IN uF/WV.
ALL CAPACITORS ARE IN pF/50WV UNLESS OTHERWISE NOTED.
EX) 030 3pF 330 33pF 331 330pF 333 0.033uF
ALL RESISTORS ARE IN OHMS 1/4WATTS UNLESS OTHERWISE NOTED.
THE THICK LINES ON PC BOARD ARE THE PRINTING SIDE OF THE PARTS.
EX) PRINTING SIDE

THE COMPONENTS IDENTIFIED BY MARK ARE CRITICAL FOR SAFETY.
REPLACE ONLY WITH PART NUMBER SPECIFIED.
VOLTAGE (MEASURED WITH VOLTMETER) IS DC VOLTAGE. (NO INPUT SIGNAL)
ELECTROLYTIC CAPACITORS ARE IN uF/WV.
ALL CAPACITORS ARE IN pF/50WV UNLESS OTHERWISE NOTED.
EX) 030 3pF 330 33pF 331 330pF 333 0.033uF
ALL RESISTORS ARE IN OHMS 1/4WATTS UNLESS OTHERWISE NOTED.
THE THICK LINES ON PC BOARD ARE THE PRINTING SIDE OF THE PARTS.
EX) PRINTING SIDE

HA12167FB/HA12169FB
Audio Signal Processor for Cassette Deck (Deck 1 Chip)
ADE-207-110B (Z)
3rd Edition
Description
HA12167FB/HA12169FB is silicon monolithic bipolar IC providing REC volume system, Level meter
system and Dolby noise reduction system* in one chip.
Functions
• REC equalizer × 2 channel
• Equalizer volume × 2 channel
• Dolby B/C NR × 2 channel
• REC/PB input electronic volume × 2 channel
• Level Meter × 2 channel
• DAC for adjusting bias × 2 channel
Features
• Available to create characteristics of REC equalizer by changing external resistor, no coil
• Equalizer volume is available to calibrate recording automatically with micro-controller
• Electronic volume built-in is available to set the level of recording and play back automatically with
micro-controller
• 4 types of input (3 out of 4 are by way of electronic volume)
• Input electronic control switching is irrelevant to REC/PB electronic control switching
• Dolby noise reduction system is available with double cassette decks (Unprocessed signal output
available from recording out terminals during PB mode)
• Log-compressed level meter output is range from 0 V to 5 V (Usable as music search switchable gain of
0 dB and 20 dB respectively)
• Normal-speed/high-speed, normal/metal/chrome fully electronic control switching built-in
• NR-ON/OFF, Dolby B/C, MPX ON/OFF fully electronic control switching built-in
• Reduction of the number of pins by transfered serial data to electronic volume control switching and
another control switching (Controllable from micro-controller directly)
• Small the number of external parts

Application Note
Power Supply Range
HA12167FB/HA12169FB are designed to operate on either single supply or split supply.
The operating range of the supply voltage is shown in table 1.
Table 1 Supply Voltage
Type No. Single Supply Split Supply
HA12167FB 12 V to 15 V ±6.0 V to 7.5 V
HA12169FB 11 V to 15 V ±6.0 V to 7.5 V
The lower limit of supply voltage depends on the line output reference level.
The minimum value of the overload margin is specified as 12 dB by Dolby Laboratories. HA12167 series
are provided with two line output level, which will permit an optimum overload margin for power supply
conditions.
Reference Voltage
For the single supply operation these devices provide the reference voltage of half the supply voltage that is
the signal grounds. As the peculiarity of these devices, the capacitor for the ripple filter is very small about
1/100 compared with their usual value. The Reference voltage are provided for the left channel and the
right channel separately. The block diagram is shown as figure 1.

Operating Mode Control
HA12167FB/HA12169FB provides fully electronic switching circuits. All switches are controlled by serial
data.
Table 2 Threshold Voltage (VTH)
Pin No. Lo Hi Unit
42 –0.2 to 1.5 3.5 to 5.3 V
39, 40, 41 –0.2 to 1.0 4.0 to 5.3 V
Notes: 1. Voltages shown above are determined by internal circuits of LSI when take pin 47 (DGND pin) as
reference pin. On split supply use, same VTH can be offered by connecting DGND pin to GND
pin.
This means that it can be controlled directly by micro processor.
2. Each pins are on pulled down with 100 k internal resistor.
Therefore, it will be low-level when each pins are open.
3. Note on serial data inputting
(a) The clock frequency on CLK must be less than 500 kHz.
(b) Over shoot level and under shoot level of input signal must be the value shown below.
When connecting microcomputer or Logic-IC with HA12167FB/HA12169FB directly, there is
apprehension of rash-current under some transition timming of raising voltage or falling voltage at V
CC
ON/OFF.
For this countermeasure, connect 10 k to 20 k resistor with each pins. It is shown in test circuit on this
data sheet.
In case of changing NR-ON/OFF at the C-mode, for the countermeasure of the noise of pop, perform the
following processes.
In case of changing NR-OFF to NR-ON at C-mode. C-mode, NR-OFF → B-mode, NR-OFF → B-mode,
NR-ON → C-mode, NR-ON.
In case of changing NR-ON to NR-OFF at C-mode. C-mode, NR-ON → B-mode, NR-ON → B-mode,
NR-OFF → C-mode, NR-OFF.

Serial Data Formatting
14 bit shift register is employed.
CLK and data are stored during STB being high and data is latched when STB goes high to low.
Reset goes reset a state when reset low and high releasles reset. (High fixed at use time)
Attention Point of Serial Interface
• Reset goes low condition when a power supply is ON or OFF.
• Characteristics select of Bias DAC is connected with equalizer tape selector.
• Bias DAC register is all low when a time of tape select.
• Bias DAC register is all low and Bias DAC out is dropped low level at compulsion by force.
• Input pin select, REC/PB select and Input volume gain select does not select at the same time.
• Input volume must go mute condition when selected of RPI is input pin select.

MPX ON/OFF Switch
MPX-OFF mode means that signal from input amp doesn’t go through the MPX filter, but signal goes
through the NR circuit after being attenuated 3 dB by internal resistor. Refer to figure 5. For not cause any
level difference between MPX-ON mode and MPX-OFF mode, it is requested to use MPX-filter which has
definitely 3 dB attenuated. And when applying other usage except figure 5,
take consideration to give bias voltage to NR-IN terminal by resistor or so on because internal of NR-IN
terminal has no bias resistor.
Application as for the Dubbing Cassette Deck
HA12167FB/HA12169FB series has unprocessor signal from recording out terminals during playback
mode. So, it is simply applied for dubbing cassette decks.

Injector Current
HA12167FB/HA12169FB has logic circuit which is fabricated by I2L into IC. To operate this circuit, it is
required enough injector current. Injector current goes into from the INJ pin (pin 38) and external resistor
is required to connect to this pin for adequate current. The value of external resistor is obtained by using
following equations. And put them with ±10% tolerance value which is calculated. V
can allow to
INJ
connect to VCC shown below. Large injector current fear to cause mis-operation of Logic under the
condition of high temperature. Also, small injector current fear to cause mis-operation (stop operation).
Under the condition of low temperature. Therefore, pay attention to have good stability of V

Gain Control of Electronic Volume
HA12167FB/HA12169FB is designed in order to change the gain by DAC fabricated into IC. To reduce
the click noise when changing volume gain instantaneously, required to connect the capacitor and resistor
(CR time constant) to CONT pin (pin 13, 48, 68, 73). These terminals are also be used as output pin of
DAC. Therefore, by forcing voltage and current to these terminals, it is applicable to control volume gain
directly. But, voltage forced to these terminals must be from VCC/2 –2 V to VCC/2 (for split supply use, –2
V to 0 V) in this case. And, this case, change of a gain depending on a temperature gets large.

When the (variable) width of the DAC step is to be changed, the gain at step 0 or at step 63 must be
changed. The step 0 gain can be changed using R’GP as shown in figure 13. Also, R’GP can be switched
using the tape selector, as shown in figure 15. However, it is necessary to take into account that the value
of R
, which sets the step 63 gain, is also used for the output bias. When the load resistance on pin 33 is
